Subscription Workflow Project Template in Java

This project template illustrates the design pattern for subscription style business logic.

Setup

Build the project:

./gradlew build

Run the Temporal Server in another terminal:

git clone https://github.com/temporalio/docker-compose.git
cd docker-compose
docker-compose up

Start

Start the Workflow Executions:

./gradlew -q execute -PmainClass=io.temporal.sample.starter.SubscriptionWorkflowStarter

This will start Workflow Executions for 5 customers with the following Ids:

Id-0
Id-1
Id-2
Id-3
Id-4

Get billing info

You can Query the Workflow Executions and get the billing information of a specific customer. Pass in an Id of an existing subscription customer (e.g. "Id-0").

./gradlew -q execute -PmainClass=io.temporal.sample.starter.QueryBillingInfo --args="Id-0"

Update billing

You can send a Signal a Workflow Execution to update the billing cycle cost for a specific customer. Pass in the customer Id and the amount (e.g. "Id-0 300").

./gradlew -q execute -PmainClass=io.temporal.sample.starter.UpdateBillingCycleCharge --args="Id-0 300"

Cancel subscription

You can send a Signal to Workflow Execution to cancel the subscription for a specific customer. Pass in the customer Id (e.g. "Id-0").

./gradlew -q execute -PmainClass=io.temporal.sample.starter.CancelSubscription --args="Id-0"
